The stem tapers upward from the socket at its base. It is yellowish and covered with loose fibrils of darker hue. The ring is white, but frequently tinged with yellow. In taste and smell it is mild. Open woods is its favorite habitat, yet it is found growing luxuriantly under pines, maples, elms, on lawns. It is not often found, but when it is, it is solitary, or in groups or rings. In the latitude of Philadelphia it is found from July until October 1st. Further south its stay conforms to temperature, and it is more frequent. There is no doubt of its rare edibility abroad, and of its being eaten in America. A specimen believed to be it should never be eaten until carefully distinguished from A. muscaria and A. Frostiana, which have warts or scales on the cap (which sometimes are not discernible after rain), white gills, and a volva which soon breaks up into fragments or scabs. Appearing like a small form of A. muscaria, to which it was formerly referred, is A. Frostiana Pk. (Frost’s Agaric). It closely resembles small A. Cæsarea, especially in the yellow tinge of stem, ring and gills. The volva and ring (persistent in A. Cæsarea) soon disappear, but are traceable by fluffy fragments, or yellow stains. It is extremely poisonous. The differences, concisely, are these: A. Cæsarea (Orange Amanita). =Cap= smooth, though occasionally with a few fragments of the volva as patches upon it. =Gills= yellow. =Stem= yellow. =Volva= usually persistent, sometimes breaking up into soft, fluffy masses. _A. muscaria_ (Fly Amanita). Poisonous. =Cap= covered with remains of the volva as scales or wart-like patches. =Gills= white. =Stem= white or light-yellow. =Volva= not persistent, breaking up into fluffy fragments or scales. _A. Frostiana._ Poisonous. Smaller and more delicate than the two preceding. =Cap= smooth or with yellow scales or wart-like patches. =Gills= yellow or tinged on edge with yellow. =Stem= white or yellow, the ring evanescent, but always leaving a yellow mark on stem. =Volva= yellow, breaking up into yellow fluffy fragments. Far better for the amateur to let the A. Cæsarea, and anything resembling it, respectfully alone. New York, _Gansvoort_. Circle forty feet in diameter. _Peck_, 32d Rep.; Maryland. There is not a doubt that this fungus can be eaten with impunity, _Banning_; Alabama, abundant. Edible. Alabama Bull. No. 80. Rogues and Cordier, French writers, regard it as the finest and most delicate of fungi, the perfume and taste being exquisite.
